Biopolymers for Geotechnical Applications
A number of bacteria, e.g., Alcaligenes eutrophus, have been employed to produce large amounts of intracellular polyester, poly-β-hydroxy butyrate...

Retention of Multiple Heavy Metal Ions by Fly Ash
Clayey soils are widely used as liner materials in landfills. They, not only retard the transport of leachates due to their low permeability, but also retain the heavy metal ions due to...

A Process Unit Based Approach to Media-Integrated Waste Minimization: A Paint Manufacturing Case Study
Research conducted at the School of Engineering, University of Guelph, has developed a media-integrated waste minimization plan for a major Ontario paint and coatings manufacturer. The...

New Block Copolymers for Membrane Materials
New fluorine containing polymer materials, which contain n-fluoro octylacrylate (pFOA) or n-fluorooctylmethylacrylate (pFOMA) repeating units, are being explored for use in thin film composite...

Use of Artificial Neural Networks for Agricultural Chemical Assessment of Rural Private Wells
The detection of agricultural chemicals in rural private wells has prompted for numerous studies at regional, state, and national levels. A principal concern arises from the fact that...

Identifying Potential Trophic Relationships and Bioaccumulation Pathways between Fish and Invertebrates
A large ocean monitoring database was used to quantify relationships between demersal fish, epibenthic macroinvertebrates (EMI) and benthic infauna that provide potential pathways for...

Biodegradation of Dichloromethane in Leachate
The biodegradation of dichioromethane (DCM) in landfill leachate is examined by means of a series of laboratory tests conducted in a controlled environment. These tests demonstrate that...

Bacterial and Chemical Pollution of Littoral Waters of Lake Ohrid at Pogradec—Town Area
The Pogradec shore waters exceed these bacteriological standards and provide risks to the public health. The levels of the chemical indexes clearly show the influence of organic pollution....

Overview of DoD Research in Groundwater Modeling
The U.S. Army Engineer Waterways Experiment Station leads a multi-agency research program for the Department of Defense (DoD) which continues the development of integrated, comprehensive...

The Case Against Markets
Markets are much in vogue as ideal institutions for managing water both nationally and internationally. True markets, however, have seldom existed for water rights and there are good reasons...

Immobilization of Metals and Solids Transported in Urban Pavement Runoff
Urban areas in North America continue to grow in size and population. With this growth is an increase in automotive traffic, roadway pavement and deleterious anthropogenic constituents....

Channel Restoration of Incising, Mixed Grain Size Streams: Lessons Learned
Aquatic habitat restoration in incising sand and gravel bed streams disturbed by channelization and other human interventions has received little study. These channel systems are characterized...
